Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If initial processing of wireless communication connection is partially omitted to reduce latency, then data transmission time is reduced, but communication accuracy deteriorates
Solution Approach 1:
The patent changes the frequency parameter by extending the frequency range for transmitting the first signal when uplink synchronization is not performed. This allows the system to compensate for the lack of initial processing by using a broader frequency spectrum, thereby maintaining communication accuracy while enabling faster data transmission without conventional synchronization procedures.
Solution Approach 2:
The patent performs preliminary frequency range extension and resource element selection before data transmission begins. By pre-configuring the extended frequency range and selecting appropriate resource elements in advance, the system prepares the communication parameters needed to maintain accuracy without performing full initial connection processing at the time of transmission.
2Productivity
If multiple wireless communication terminals transmit data to mobile base station simultaneously, then data transmission efficiency improves, but connection failures and delays increase
Solution Approach 1:
The patent segments the frequency range into multiple resource elements for different terminals. By dividing the extended frequency range into distinct resource allocations, the system allows multiple terminals to transmit simultaneously on different frequency resources, reducing collisions and connection failures while maintaining high transmission efficiency.
Solution Approach 2:
The patent introduces frequency range extension as an additional dimension for resource allocation. By utilizing frequencies outside the conventional range and mapping resource elements across this extended dimension, the system creates more separation between simultaneous transmissions from multiple terminals, reducing interference and improving connection reliability.
3Measurement precision
If frequency range is extended for data transmission, then communication accuracy is maintained, but system complexity increases
Solution Approach 1:
The patent performs frequency range extension and resource element selection in advance before data transmission. By pre-configuring the extended frequency parameters and resource mappings, the system avoids complex real-time calculations during transmission, reducing operational complexity while maintaining accuracy benefits.
Solution Approach 2:
The determination unit autonomously determines whether to extend the frequency range and selects resource elements based on predefined criteria and current transmission needs. This self-service approach eliminates the need for complex centralized coordination, allowing the system to manage extended frequency ranges with reduced operational complexity.
